I have never had a problem either. Although, I would not use a pressure washer. If you are getting water in your plug wells, then you did not have a good seal to start with. Plus, you should spray directly on top of the boots. Oh well... I will continue to wash like I always have.
When I was learning to fly a few years ago, one thing I was told countless times is that there are two types of pilots:
1. Those who have had a gear-up landing
2. Those who will
(for those who don't know, a gear up landing is one where the pilot fails to lower the landing gear and ends up doing something akin to a $20000 belly-flop on the runway).
In over 1500 hours of flying I've yet to do it, and try to never let myself stray from my pre-landing checklists and procedures, but despite that I still suspect that despite my best efforts, one day in the very distant future, I will.
As I've said in similar threads, I think that this whole engine washing debate really comes down to the same concept. To me, it just seems like too much of an unnecessary risk given the potential consequences. We spend so much time and effort on these cars, that to short-cut under-hood cleaning with a spray-on product and running water seems illogical when a rag, cleaner, and a little elbow grease will work just as well.
It's alot like the drunk drivers who don't **** someone on their first, second, or even 100th time driving drunk. Just because it hasn't happened yet, is it worth continuing to take the chance???
